There was one enemy in Kingdom Hearts I really hated to fight.
They've recently released a mobile game called KHux and at certain intervals a Raid Boss will appear who blocks game progression unless defeated or the timer runs out:
Yes, that is the one enemy from Kingdom Hearts I hate!
And it's even meaner in this version, just one attack and you are defeated!
In case that wasn't bad enough, look at the level disparity.
My character is Level 18, the Raid Boss is Level 1!
I am thinking the terrified expression on my character's face is quite appropriate, given this situation.
